GEORGE W. COPEI-LAND, OF MALDEN, MASSACHUSETTS. l

HEEL-LASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 329,281, dated October 27, 1885.

Application tiled August 3. 1885. Serial No. 173,352. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE W. Corn- LAND, of Malden, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and vuseful Improvement in Heel-Lasting Devices, of which the following is a full, clear, and exact description, reference being had to the accompan ying drawingsforming apart of this specification, iu explaining its nature.

The object of the invention is to provide means for fitting the heel-section of a boot' or shoe to the heel end of the last, and to break over and fold down the margin thereof suffi-- ciently to enable the operator to fasten the same, and thus complete the operation by turning it,while the upper is held clamped to the surface of the last and the edge of the insole by clamping devices or abutments,so that the same may be finished by a hand-tool.

l use in this invention the abutments or devices shown and described in my application for Letters Patent filed May 27, 1885, Serial No. 166,839, and in addition thereto Iemploy a number of breakdown irons or devices ofi surface of the insole while the upper is beingl held by said abutments.

The invention further relates to various details of construction, all of which will be more especially referred to hereinafter.

Referring to the drawings, Figure l is a side elevation of a machine containing the features of my invention. Fig.2 is a plan view thereof. Fig. 3 is a front elevation of the upper part or head thereof. Fig. 4 is averticalsect-ion upon the line .fr .fr of Fig. 2, including that portion of the head shown in Fig. 3. Figs. 5 and 6 are detail views. Fig. 7 is a vertical section enlarged to represent the operation of the device in folding or breaking down the edge of the Lipper.

The abutmentsA A', preferably, are hinged at a, and have closing and opening movements imparted to them, as hereinafter specified, and there is arranged to project or extend through the holes or passages a', formed therein, a series of breakdown-irons, B, the

under surfaces, b, of which, preferably, are

inclined as represented in Fig. 7. Theseirons are carried by the abutments, and are adapted to be brought into operation or moved horizontally after the abutments have been closed upon the heel end of the last. The abutments are supported by the block B', and have a horizontal movement on the block B, and in the operation of lasting the heel the first movement given them is to advancethem or move them against the extreme heel end of the last. This is done by means of the sliding block C, which has a wedge or inclined surface, c, against which the roll c upon the end of the lever c2, pivoted at c3, bears, and this lever carries or supports the spring-arm c, that bears against the blocks A A', so that upon the movement of this sliding block C down the lower end of the lever is thrown outward land the spring-arm inward, thereby moving the blocks A A toward the heel end of the last and bringingthe abutments or jaws in contact therewith. This movement is immediately followed by the closing movement of the abutments or jaws upon the heel end of the last to clamp the upper thereto and to the edge of the insole and to hold it supported,as described in my said application. This is done by providing the operating-block C with two inclines, c, one on each side, against which -bear the rolls c6 upon the lower ends of the 1evers, pivoted, respectively, at c7 cs, and these levers also bear aspring-arm,c, which connects them with the sides of the abutments at ci", so that by a further downward movement of the operating block the lower ends of the levers are moved outward and the spring-arms forced inward, closing'the abutments upon the surface of the heel end of the last. This closing movement of the abutments is immediately followed by the inward converging movement of the breakdown irons B, and this also is brought about by the further downward movement of the .operating-block C, the portions D thereof coming in contact with the heads d of the rods d, fastened to the spring-carriers B3 B3, situated outside the head or block B', (see Fig.4,) in a manner to permit of theirhorizontal movement with reference to the bolts d. To these carriers are attached springs di, which take hold of rods d3, extending upward and connecting the lasting devices B by means of the links di, (see Fig. 4.,) and these are also arranged to lift the rods da, springs d5.

Of course, I do not confine myself to the cspecial means herein described for operating the abutments or the irons, but may useany mechanical equivalents therefor. There is a spring clamping-band, E, as represented in Fig. 2, which is adaptedto be brought against the heel end of the last by the wedge-.block e, carried by the abutments A, shutting upon the wedge-block e', carried by the band E.

In operation,the boot orshoe is placed upon the last, which is supported by its jack, and the heel-lasting device brought to bearagainst the heel end, as above described, and the abutments closed. The inward movement of the breakdown-irons causes portions of the edge or margin of the upper to be folded or broken down near the surface of the insole, leaving spaces between them for the reception of the i'astenings, which are then driven. 'Iheirons are then withdrawn and other fastenings may be driven,if desirable, and the lasting is substantially complete. It may be finished with a hand-tool. It will be seen that thebreakdown-irons and abutments are automatically returned to their original or normal position on the release of the operating-block by the springs d5; also that the abutments are open and thrown back upon the release of the operating-block and its upward movement by means of the springs.

Instead of moving the abutments vertically, as described in said Copeland application, I provide the jack with a vertical movement, so thatv the last is moved vertically in relation to the abutments, instead of the abutments being moved vertically in relation to it, and, as there are so many different forms of jack provided with this movement, I have thought it unnecessary to describe such construction here, and have simply shown the pin F. The block C is operated, preferably, by the connecting-rod g (shown in Fig. 4 and in dotted line in Fig. l) and the treadle g', pivoted at g2, and there is arranged a latch, g3, for locking the treadle g' in its lowest position. A spring, g, acts to lift the lever. It will be seen that the springs d act as compensators, in that they allow the spring-carriers Bi to be drawn downward vertically sui-ficiently to close all .the irons B. It will also be seen that the abutments and the workingsurfaces of the irons bear such relation that the abutments act, as specified in my said application, to support the upper at and above the edge of the insole, and to serve as a guide for the folding tool, and that the irons serve to break down and fold over the margin ofthe upper sufficiently to permit the fastening of the sections of the upper betweenv them to the insoleand tocomplete the turning-down pro cess. It will be understood that by these operations the act of fastening completes the turning operation.

Having thus fully described myinvention, I claim and desire to secure by Letters Patent of the United States- 1. In a heel-lasting device, the combination of the abutments A A with the series of converging breakdown-irons B, all substantially as and for the purposes described.

2. The combination of the last-support F, the abutments A A', and means, substantially as described, for moving the abutments toward the last with a yielding pressure, all substantially as and forthe purposes described.

3. 'Ihe combination ofthe abutments,break down irons B, and means, substantially as specified, for operating the same, all as and for the purposes described.

4. The combination of the last-support, the last, the movable abutments, and the breakdown-irons, and means, substantially as described, for moving the abutments toward the last for closing the same thereon and for operating the breakdown-irons, all substantially as described.

5. In a lasting-machine, the breakdownirons B, having the inclined or wedgeshaped operating-surface b, substantially as described.
